MENINGIOMAS OF THE CEREBELLOPONTINE ANGLE

Meningiomas of the cerebellopontine angle are the second most frequent type of tumours in that region and constitute more than one-third to one-half of all meningiomas of the posterior cranial fossa. On account of their vulnerable position in relation to the cranial nerves and du e to the lack of available space, good postoperative results and a min imum of cranial neurological deficits can be achieved only if they are identified well in time and surgically removed. Basing on case histor ies and follow-ups of 15 selected patients, preoperative and postopera tive symptoms of meningiomas of the cerebellopontine angle are discuss ed, possible misinterpretations pointed out and recommendations worked out to achieve an early clarification or surgical treatment.
